I have bought this on the 8th of August with next day delivery as a suprise. I added the batteries and tested it worked fine. Came to use it for the first time doesn't work. I paid over seven pounds for next day delivery. the item has not been used and its doesn't work . If its defective ok. will see what seller says but 1 star i enough for what this costs. I will update better if resolved quickly and effiently.
